To (ill whom it wry concern..-

Be it known that we, bixnilint M. CURWEN and Waiunas ill. h m-r11,citizens of the United States, residing, respectively, in llu orl'ord,t'etrnsylvaniu, and minutes, rennsylvania, have invented certainimprovements in lusscr1ger;()ars, of which the following is aspecification.

Our iint'niion relates to certain improrements in passenger cars of thetype in which a door is provided at one or both sides of the platformand of the type in. which a movable step is used so that when the stepis not in use it can he moved out of posit1on.

()nc object of our invention is to provide nit-ans for closing the spacebetween thebottom of the door and the floor of the platform withoutcutting away the sills forming the fl;tlllt\\0ll{ oi' the car; and afurther object of the in rention is to actuate this closing means on themovement of the step. These objects we attain in the following manner,reference being had to the accompanying drawing, in which:

Figure l, is a transverse sectional view on the line l-l, Fig. 4,through a portion of the platform; the step .being lowered and the doorbeing open; Fig. 2,,is a. view similar to Fig. 1, showing the stepraised and the door closed; Fig. 3, is a transverse sectional view onthe line 3-3, Fig". 4; and Fig. 4, is a side view of a portion of theplatform of a car; the stop being in the positionvillustrated in Fig, 1.

In the accompanying drawing, A is the body of the car and B is theplatform. The floor 6 of the platform is some distance be-.

loiv the floor a of the car body and the transverse sill forming part ofthe framing of the car is directly under the floor a and consequently ifthe sill is cut away it weakens the car framing considerably and yet itis desirable in many cases to providea sliding door at the side of theplatform so as to close the passageway, leaving the doorway 0 en betweenthe platform and the body of t e car.

D is the sliding door for closing one side of the platform and thissliding door is adapted to a channel in the body of thecar, but. inorder to obviate the necessity for cutting away the sill of the car, wcmount the door' so that it. will slide above the sill. lVhen this door,however, is closed there is a space left; between the bottom of the doorand the tloor'of the platform and one object; of the present inventionis to close this space.

this step is secured to a pivot shaft a mounted in brackets F fastenedto theunderside of the framing of the platform and projectingfrom thesebrackets are fixed supports upon which the step rests when in theposition illustrated in Fig. 1, so that. )assengers may enter or leavethe car. he pivot shaft tn on. which the step is mounted has a bevelgear 0 which'meshes with the bevel wheel 5 on a vertical shaft G, having at its upper end a pinion i which meshes with a rack (Z on the doorThis rack is so located and the mechanism is so timed that the step willnot be raised tintil the door is partly closed and on the first movementto open the door the step is lowered, thus preventing the tripping ofpassengers endeav 'oring to-board or leave the car during the firstmovement of the.closing of the door.

Mounted on the underside of thcstcp near shaft; I carrying a su)plemental door I, and mechanism is provied so thpt the door swingsunder the step E when it is lowered and in the position illustrated inFig. Land .when the step is raised, as shown in Fig. 2, the door I isturned on its pivot and rests either directly under or against the doorD, closing the space between the main door D and the support of thelatform. In the present instance we provi e a pinion 2' on the shaft I,which mshes with a rack par N pivoted at a to the bracket at a point;below the pivot e of the step. i

The parts are so proportioned that as the step is turned on its pivotfrom the position shown in Fig. 1 to-that shown in Fig. 2 the shaft;from the position under the step, as in Fig. 1, to the ing the spaceetween the main door D and the floor of the platform. Other means may beresorted to for confining the movement of this hinged supplemental doorWithout. departing from the main features of our in-- .vention. 1

step at. one side of the platform, it; will be understood thatwhendesired both sides of E is a step at the side of the platform andosition shown in Fig. 2, clos- While we have shown in the drawings the"the platform may be provided with this supplemental door I will beturned on its mechanism, but where the platform is closed on one side,then the above described mechanism is only necessary on the en side.

\Ve do not claim broadly in t iis application the supplemental door forclosing the space between the main door and the bottom of the platform,nor do we claim broadly the two doors connected so that they wil work inunison so that the supplemental door will be actuated on by the movementof the main door, as this is fully set forth and claimed in anapplication for Patent filed by as of even date herewith.

\Ve claim z- 1. The combination in a passenger car in which the floor ofthe platform is below the end sill of the car body, of a sliding doormounted above the sill and arranged. to extend over the platform, a,movable step and a supplemental door, with means connecting thesupplemental door and the step with the sliding door so that on theclosing of the door the step will be raised and the space between thesliding door and the floor of the platform will be closed by thesupplemental door.

2. The combination in a passenger car, in which the floor of theplatform is below the floor of the body of the car, of a sliding doormounted above the sill of the car body and arranged to extend over theplatform, with a movable step and a supplemental door carried by thestep, with means connecting the step with the sliding door so that onthe closing of the sliding door the step willbe raised and thesupplemental door will be i moved into position, closing the space he ltween the main door and the floor of the 1 platform. l

8. The combination in a passen 1' car in which the floor of the platformis low the end sill of the car, of a sliding door mounted above the sillof the car body and arranged to extend over the platform, a pivoted stepat one side of the latform, gearing between the step and the slidin doorso that on the closing and opening 0' the sliding door the step will beraised and lowered, a supplemental door pivoted near the outer end ofthe step, and means for turning the supplemental door on its pivot asthe step is raised and lowered so that when the step is raised and thesliding door closed the supplemental door will close the space betweenthe sliding door and the floor of the platform.

4. The combination in a passenger car having a platform, the floor ofthe platform being below the upper surface of the end sill of the car,a. sliding door adapted to close one side of the platform and mountedabove the sill, a step pivoted to bearings at one side of the platform,a pivot shaft mounted on the step near its outer end, a supplementaldoor carried by said pivot shaft, a

pinion on said shaft, and a rack engaging said pinion and pivoted at afixed point at some distance from the pivot of the step so that as thestep is raised a rotary motion will be imparted to the supplementaldoor.

In testimony whereof, we have signed our names to this specification, inthe presence of two subscribing witnesses.
